Seems like just a bid to create a revenue stream on selling the bottom valve cups. Fast food places have been using automatic fill from the top for sodas for years, it dispenses a set amount for a size of cup. You could easily adapt it for beer by varying the dispensing speed. Heck if I recall correctly one of the systems even drops the cup for the size ordered on a conveyor, fills it, and then all the employee needs to do is put a lid on it and hand it out.

Yep - beer has more head retention than soda. The key for fast filling like this is to avoid turbulence that will take the CO2 out of solution and create foam.

For best results, though, the carbonation level of the beer needs to be reduced. The amount of carbonation in American lagers is designed to still have bubbles after the gas loss of a regularly pour. If you keep all that CO2 in the beer, it comes out in the drinker's stomach, causing belches and an unpleasant full feeling.

Any repetitive motion can be automated. The angle of the glass, when to stop etc... It's just a matter of engineering and it being cheaper to use the machine than a person. If minimum wage laws continue the way they have been, that's going to become economical to built. Or most places will switch to bottles/cans to save labor.
